Before spend-and-save and a coupon stack, write who calculates first
Campaign operations writes the stacking order of spend-and-save, gifts, and coupons as rules that can be judged. Coupon lists sit with user operations. Taking old copy down sits with content operations.
| Condition | Result | After it ends |
|---|---|---|
| Order paid, amount reaches 200 | Minus 20, before the coupon | Refund on amount actually paid, not original price |
| Specified coupon and not deactivated | Deduct after spend-and-save, once per order | Coupon is not returned unless the whole order is cancelled and not shipped |
| Gift stock short | Must not silently drop the gift at order | Missing gift goes on a reship document; do not change historical amounts |
Campaign operations writes promotion as rules, not as a poster
A poster can say spend-and-save and coupons are issued for a limited time. The mark of campaign operations is locking calculation order, mutual exclusion, refunds, and short gifts before the campaign starts, and handing that to product to confirm. An unwritten “can be combined” lets each store calculate its own way. He trial-calculates orders: one that meets the threshold, one just short, one with a stacked coupon, one a minute before start, one a minute after end. All five amounts must be predictable. If they cannot be predicted, the campaign does not start.
He confirms the issue list with user operations, and with finance that revenue is on amount actually paid. Campaign operations does not change price master data. Changing master data affects non-campaign orders. Discounts should stay in the order’s discount lines, so afterwards these twenty yuan can be explained from which rule.
End and review
When end time arrives, the rule stops by itself. It does not rely on someone remembering to flip a switch. After it ends he checks: total discount, issued count, redeemed count, unredeemed, refund clawback. Orders that do not match are listed by document number. The review does not write “the effect was good.” It writes which rule was misused. Misuse goes into the next campaign’s forbidden items.
The campaign that stacked coupons and over-discounted
A spend-and-save allowed combining with coupons, but did not write order, and did not write once per order. Some stores stacked two coupons, and amount actually paid fell below cost. Campaign operations paused coupon stacking, listed orders already produced for finance, and did not silently change historical amounts. The rule became: after spend-and-save, only one coupon. Trial calculation passed, then it reopened. Poster copy dropped “more coupons, better.” Content operations took the old copy down. Loss from this campaign was limited to documents before the pause, not the whole weekend.
Trial-calculation records and the rule table stay in the campaign file. The next campaign is not allowed to reverse-engineer rules from a poster. Before start, campaign operations trial-calculates one refund. If the refund amount goes back to original price instead of amount actually paid, the rule cannot go live. He puts the trial-calculation screenshot in the file. A campaign with no refund trial calculation: finance finds under-refund or over-refund on the first return, after coupons have already gone out. Short gifts must also be written on the campaign page. The page says a gift, the order has no gift line, and support can only soothe with a coupon. Soothe cost will not appear in the campaign budget. It will appear in gross margin. He puts that cost into the review, so the next campaign does not reuse the same “can be combined.” Whether unredeemed coupons expire void or return as balance must be in the rule table before start, not soothed on the spot. The rule version number stays in the campaign back office and on the order discount line. How the poster is written, and how old copy comes down, sits with content operations. This role only guarantees an order can explain, from the same rule table, why twenty was taken off.
The five trial calculations must leave amounts. Spend 200 save 20, then stack a 30 coupon: amount actually paid must be 150, not 150 minus once more. An order at exactly 199: spend-and-save does not apply; the coupon still deducts per the rule. An order a minute before start follows the old rule. An order a minute after end follows original price. Refund trial calculation refunds amount actually paid, not original price. If one of the five cannot be predicted, the campaign does not open. Coupon lists are produced by user operations from live identity. This role does not send a second copy in a poster group. Discounts stay on the order line and afterwards can point at the rule version number. Reverse-engineering rules from a poster is a forbidden item for the next campaign.
